SPECIFICATION forming part of Letters Patent No. 794,700, dated July 11, 1905.

Application filed March 18, 1905. Serial No. 250,728.

To all whom it may concern.-

Be it known that 1, WILLIAM T. CARROLL, a citizen of the United States, and a resident of V Vorcester, county of Worcester, State of Massachusetts, have invented an Improvement in Ring Spinning or Twisting Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings IO representing like parts.

This invention relates to spinning or twisting apparatus wherein a revoluble traveler loosely cooperates with the flanged head of a ring through which the spindle extends, the

I 5 revolution of the traveler being effected by the pull of the yarn as it passes therethrough to the bobbin. As is well known to those skilled in the art, the traveler is thrown outward with very considerable force by cen- 2o trifugal action against the interior of the ring,

so that the inner end of the traveler wears rapidly and destroys the traveler, especially at high spindle speeds. Ordinarily an increase of the weight of the traveler to increase its 2 5 resistance to wear improperly increases the tension on the 'yarn, such increase in weight being effected by increasing the cross-section of the wire from which it is made.

My present inventionhas for its object the 3 production of a novel and improved traveler so constructed that while it may be made of considerably greater weight than is usual it will not increase the tension on the yarn.

By reason of the peculiar shape of my novel traveler it will wear much longer, and it will also stand very much higher spindle speeds, as it will not heat up and lose its temper, as will a traveler of ordinary construction.

The traveler is so shaped that it can be rap- 4 idly and easily made, the wire being of uniform cross-section throughout, the preponderance of weight being located inside of the r1ng.

The various novel features of construction of my improved traveler will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure l is a cross-sectional view of a wellknown form of spinning or twisting ring with a traveler cooperating therewith embodying one form of my invention. Fig. 2 is a side elevation of the traveler detached. Fig. 3 is an edge view thereof viewed from the left,

Fig. 2; and Fig. 4 is a view similar to Fig. 1, but showing the ring provided with a supplementary internal flange or rib, to be referred to.

In Fig. l I have shown in diametral crosssection a spinning or twisting ring of wellknown construction of the reversible type and comprising an annular vertical wall or web 1 and a double flange 2 3 at each end thereof, the uppermost one when the ring is in use constituting a head or raceway for the traveler.

In accordance with my present invention the traveler comprises a bow-shaped body portion 4: of substantially conventional shape adapted to embrace loosely the head of the ring, the ends of the body being inturned, the outer end at 5 to extend beneath the outer flange 2 of the ring-head, The inner end 6 is not inturned so sharply, and it is prolonged to form an extension or tail 7, depending from the body 4:, substantially at right angles thereto and in the plane of the body. Such prolongation augments the weight of the traveler on the interior of the ring, and, as shown in Fig. 1, the extension 7 bears against the inner face of the vertical wall 1 of the ring when the apparatus is in use, but only at a distance from the flanged head of the ring. The inner end of the body is thrown outward by centrifugal action to engage the inner edge of the flange. I prefer to make the traveler of flattened wire of uniform cross-section.

A traveler made in accordance with my invention contains more metal than an ordinary traveler, and consequently is heavier; but in actual use it brings no more tension on the yarn, due, probably, to the better balance of the traveler by reason of the depending extension, which bears against the interior of the ring-wall at a distance below the flange. Inasmuch as my improved traveler contains more metal than usual, it will wear longer and will also stand very much higher spindle speeds, as it will not heat up and lose its temper, which is the case with a traveler of very small cross-section. The traveler is very easy to manufacture, as will be manifest to those skilled in the art.

In Fig. 4 I have shown my traveler applied to a ring having an annular flange or rib 8 on the inner face of its vertical wall, the extension 7 of the traveler bearing on such supplementary rib when in operation. As the rib is transversely convex, it will be seen that a very small contact-surface exists between the rib and the traveler extension, reducing the wearing-surface to a minimum.

In both Figs. 1 and L the traveler is shown in substantially the position it' will assume when the apparatus is in operation, the hooklike end 5 of the body engaging the outer flange 2 of the ring and the extension 7 contacting interiorly with the vertical Wale or web portion of the ring.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a spinning-ring traveler having a substantially bowshaped body portion and a depending elongation or tail adapted to engage the inner face of the vertical ring-wall only at a distance below the head of the ring.

2. As a new article of manufacture, aspinning ring traveler having a body portion bowed and inturned at its ends to loosely embrace the flanged head of a ring, the inner end of the body being adapted to bear against the inner edge of the head and having a depending prolongation in the plane of the body, to engage the web of the ring only at a distance below the head.

3. As a new article of manufacture, a ringtraveler having a depending extension adapted to contact with the inner face of the web of the ring at a distance below the flange of the ring, and bent to clear the under side of the flange and the immediately-adjacent portion of the web.

4. As a new article of manufacture, a trav eler having a hook-like portion at one end to extend under the outer flange of a spinningring, and a prolongation or tail at the other end, substantially at right angles to and lying in the plane of the hook-like portion, to bear against the inner face of the web only at a distance below the inner-flange of the ring.

5. In spinning or twisting apparatus, in combination, a ring having aflanged head and an internal supplementary flange or rib, and a traveler having a tail or extension to bear against said rib.

6. As a new article of manufacture, a ringtraveler made of flattened wire bent to form a body having its outer end inturned to form a hook, and having its inner end prolonged to form an extension having its extremity substantially at right angles to said inturned end and curved between said extremity and the body to clear the inner face of the web of the ring adjacent the head thereof.

In testimony whereofl. have signed my name to this specification in the presence of two subscribing witnesses.
